When latency is too high, you can see that the audio doesn’t properly sync with the video.

Latency: Latency refers to the time delay between the audio and video parts of the signal.We quickly found that we preferred the less ambiguous control schemes, especially when pairing to multiple devices. Some offered only one button and one light for us to control everything and see the status, while others had more advanced (and easier-to-use) systems. Controls: Despite the relative simplicity of these accessories, their controls varied widely.

After pairing the headphones, we then paired a Bluetooth speaker to the models that connected successfully to see how they handled outputting to two devices. Although Bluetooth can be somewhat finicky, and a failure here doesn’t mean a given model will never work, you need to be able to rely on a consistently smooth process. Some connected instantly, as we expected, but a shocking number simply didn’t, even after repeated attempts. Ease of connection: We started by pairing, or attempting to pair, a set of headphones with each transmitter.

And we wanted them to be able to play audio through the TV or soundbar at the same time they broadcast the audio wirelessly. We chose to test only those transmitters that had both an optical audio input and output, allowing the audio to pass through to your soundbar (or other audio device), if you use one, rather than hijacking the signal altogether. Optical output, audio pass-through, and simultaneous output (for TV-based models): We noted a few additional considerations for stationary models intended for use with a TV.Some of the TV-based models also have batteries, but that’s simply a nice-to-have feature, as such models are most often used in a semipermanent, stationary position. We saw advertised battery life ranging from eight to 20 hours among these models even the low-end figures are pretty good and wouldn’t exclusively disqualify a transmitter.

A long battery life (for portable models): A long-lasting battery means you’ll be able to use your portable transmitter on trips or throughout the week without having to be constantly charging, and there’s a better chance that the device will be ready to go whenever you pick it up.

Even so, this guide focuses on the Bluetooth transmitting function if you’re looking specifically for a Bluetooth receiver, we have other guides for that-namely, guides to the best Bluetooth headphone adapter and the best Bluetooth audio receiver for your home stereo or speakers. Since the prices of transmitter/receiver combos were in the same range as those of transmitter-only models, we decided to limit our test to those that included both modes for added convenience.

Both transmitter and receiver modes: Although all these devices can beam audio to your headphones, some of them can also receive audio from your phone and pass it through to wired headphones, a speaker, or a car stereo.

Multi-device pairing: Because most of the models we researched can connect to two Bluetooth receivers at once (your headphones and your partner’s, for example), we eliminated any that connected to only one device.
